This study presents high-precision analyses of stable potassium(K)isotope ratio using the recently-developed,collision-cell multi-collector inductively coupled plasma mass spectrometry(CC-MC-ICP-MS,Nu Sapphire).The accuracy of our analyses is confirmed by measuring well-characterized geostandards(including...
Sapphire from Nu is a next generation Multi-Collector ICP-MS. The collision cell capable instrument builds on the field proven Nu Instruments Multi-Collector ICP-MS platform (with over 170 installed instruments worldwide) to add unrivalled capabilities. The Sapphire features high and low energy swit...
A tandem collision/reaction cell for an inductively coupled plasma-mass spectrometry (ICP-MS) system includes a first ion guide, a second ion guide, and an intermediate electrode in the vicinity of an exit end of the first ion guide. A DC potential barrier is applied to the intermediate elec...

To calculate the distance between recording-site and cell body, values are needed for the collision interval between antidromic and succeeding orthodromic spkies, the refractory period of the spike, and the antidromic conduction speed. Problems may arise in determining the last value. The method is...
